   There is a JSR on OpenGL/JoGL so I guess it made its way into the giant library by now, but I usually pick the most current binaries from the Jogle project site. You find the URL on my previous post: http://schabby.de/jogl-download/

   I hope this answers your question?

   I am having linker errors ( I have a 64bit windows 7 os, but both JVM and eclipse are 32bit so I am using JOGL 32 bit too) for some reason it says that it can’t link the native windows 32 I placed all four dlls in the class path. here is a pic of the error http://img259.imageshack.us/img259/2051/97707781.png

   Found how to run the program after days of surfing the net.

   ok, I will explain how I managed to run it and set up JOGL at the same time. https://sites.google.com/site/justinscsstuff/jogl-tutorial-1. shows how to create your own user library; once this is done I had some trouble running the dlls which I fixed by placing them in the directory of the project I was working on.

   Your example is wrong, you should never have “height” set to zero. If it happens, it means that the height of your canvas is 0. Moreover, your example won’t work with the debug pipeline of JOGL 2.0, a GLException will be thrown very early.

   Hi Julien, thanks for your post! I will correct my example as soon as i get the chance.

    Instead of adding a WindowListener for exiting the application, consider using

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    as a shortcut instead.

    Hi,

    By chance, do you also have an example how to run a jogl program as a java applet ?

    Thanks
13. schabby says:

    8. August 2011 at 20:32

    Hi!

    I am afraid I dont I never really put too much though in applets to be honest. WebGL is about to win the openGL-in-Browsers race from my point of view.

    Hello.,
    Thanks for the post., it helped me a lot., but i faced a problem while adding a jar file in eclipse. You have mentioned about adding the following jar files.,
    1. jogl.all.jar
    2. nativewindow.all.jar
    3. gluegen-rt.jar
    I could not find them on my computer, I downloaded the latest zip file from the link you have provided in your post.,
    http://schabby.de/jogl-download/
    I have downloaded the file named “jogl-2.0-b610-20111226-windows-i586.7z” under the link ” jogl-b610-2011-12-26_00-30-55″ dated 26-12-2011. unzipped the file., but i could not find all the jar files mentioned above. I could just find “jogl.all.jar”. Hope you’ll help me with this.

    Thanks,
    Yogesh.

    If you get the error

    “Can’t load IA 32-bit .dll on a AMD 64-bit platform”

    you downladed the 32-bit binaries, not the 64bit binaries.

    I tried the hello world tutorial and it will work when I run it from eclipse, however when i close the window (click the x) it still leaves and instance of javaw.exe running in the task manager. I have to manually end the process all the time. Any ideas whats causing this?
17. schabby says:

    14. March 2012 at 11:38

    Hi, the window is independent from the OS process. So closing the window does not terminate the VM. I will enhance the example to shut down the VM once the user closes the window.

    Thanks for pointing me at this!!

    Hi Ezra, you are trying to set the background of the Swing Component, which is not part of OpenGL. The command you are looking for is gl.glClearColor(...). I hope this helps, Johannes

    Hi,

    I have download and do all the stuff that you have said in the video of JOGL in Eclipse ,And after that when i run your first program ‘HelloWorld’ following error is coming.
    Can you please help me out? THX

    Exception in thread “main” java.lang.Error: Unresolved compilation problem:
    The type javax.media.nativewindow.Capabilities cannot be resolved. It is indirectly referenced from required .class files

    at JOGLHW.HelloWorld.main(HelloWorld.java:21)
24. schabby says:

    3. May 2012 at 13:13

    Hi Hardik, this is an interesting problem. Does your code completely compile? Are you sure, that you got all necessary libraries added to your classpath? If yes, do you have additional depenencies on the system, such as additional libraries that are part of your project? What JDK are you using? I myself used JDK 6 64bit.

    The problem appears to me, as if your current classpath does not contain the necessary javax.media.* stuff. What OS are you using?

    Cheers,

    Johannes

    Hi schabby, i use 64-bit wnidows 7 OS. and also my code is not compile. There is error coming in line ‘GLCanvas glcanvas = new GLCanvas(capabilities);’ saying that ‘the type javax.media.nativwindow.Capabilites cannot be resolved . it is indirectly refrenced from required .class files’
